Quick Answer: A metal carport with sides is a steel-framed shelter that combines an open carport roof with one or more enclosed side panels, offering protection from wind, rain, and debris that a standard open carport cannot provide. Costs typically range from $1,500 to $8,000 or more depending on size, gauge, and the number of enclosed sides. Most units can be DIY-assembled with basic tools, though local permits are often required before installation.
Key Takeaways
- Metal carports with sides provide significantly better weather protection than open carports, shielding vehicles from wind-driven rain, hail, and UV exposure.
- Prices in 2026 generally run between $1,500 and $8,000 for standard residential units, with larger RV or commercial-grade structures costing more.
- Most manufacturers sell kits designed for homeowner assembly, but professional installation is recommended for structures over 20 feet wide or in high-wind zones.
- Permit requirements vary by state and county; always check with your local zoning office before ordering.
- Galvanized or Galvalume steel carports typically last 20 to 30 years with minimal maintenance when properly anchored and kept clean.
- Common mistakes include choosing too thin a gauge steel, skipping permits, and ordering the wrong size for the intended vehicle.
- Metal carports with sides are well-suited for RVs, boats, trailers, and farm equipment, not just standard passenger vehicles.
- Compared to wooden garages, metal carports with sides cost less upfront, assemble faster, and resist rot and pests, but offer less insulation and curb appeal.
What Exactly Is a Metal Carport With Sides?
A metal carport with sides is a prefabricated or custom-built steel structure that features a roof and at least one enclosed side wall, distinguishing it from a fully open carport frame. The side panels block wind, rain, and direct sunlight from entering horizontally, giving vehicles and stored equipment far more protection than a bare roof alone.
These structures come in several configurations:
- One-sided: One enclosed end or side, often used to block prevailing winds.
- Two-sided: Two enclosed sides, typically the two ends or the back and one side.
- Three-sided: Roof plus three enclosed walls, leaving only the front open for vehicle entry.
- Fully enclosed: Essentially a metal garage with a roll-up or swing door added.
The frame is usually made from 14-gauge or 12-gauge galvanized steel tubing. Panels are formed from corrugated or ribbed steel sheeting, often coated with a baked-on paint finish or Galvalume for corrosion resistance. Buyers can choose from vertical-roof, boxed-eave, or regular-roof styles, with vertical roofing being the most effective at shedding rain and snow.
How Much Does a Metal Carport With Sides Cost?
Metal carports with sides cost between $1,500 and $8,000 for most residential applications in 2026, though pricing shifts based on size, steel gauge, roof style, and the number of enclosed panels. Larger structures for RVs or commercial use can exceed $15,000 installed.
Typical price ranges by size (materials only, estimates):
| Structure Size | Open Carport | With 2 Sides | With 3 Sides |
|---|---|---|---|
| 12×20 (single car) | $800-$1,400 | $1,200-$2,200 | $1,500-$2,800 |
| 18×20 (double car) | $1,200-$2,000 | $1,800-$3,200 | $2,200-$4,000 |
| 12×30 (boat/trailer) | $1,400-$2,400 | $2,000-$3,800 | $2,500-$5,000 |
| 14×40 (RV) | $2,500-$4,500 | $3,500-$6,500 | $4,500-$8,000+ |
Factors that raise the price:
- Upgrading from 14-gauge to 12-gauge steel (thicker, stronger)
- Vertical roof style over regular or boxed-eave
- Adding a roll-up door or walk-in door to an enclosed side
- Professional installation labor (typically $500-$2,000 depending on region)
- Concrete slab or anchoring system costs
Common mistake: Many buyers focus only on the base kit price and forget to budget for anchoring hardware, delivery fees, and permit costs, which can add $300 to $1,000 to the total.
Are Metal Carports With Sides Better Than Regular Open Carports?
For most vehicle protection needs, yes. A metal carport with sides outperforms an open carport whenever wind-driven rain, blowing debris, or direct sun exposure is a concern. An open carport only blocks rain falling straight down; any wind angle pushes moisture and debris directly onto your vehicle.
Where enclosed sides make a clear difference:
- Coastal or high-wind regions where rain arrives at a steep angle
- Areas with frequent hailstorms (sides won’t stop overhead hail, but a vertical roof helps)
- Locations with heavy dust, sand, or leaf debris
- Storing vehicles long-term without regular washing
When an open carport may be sufficient:
- Mild climates with low wind and minimal storm activity
- Daily-use vehicles that are driven and cleaned regularly
- Budget-constrained situations where any overhead cover is the priority
The enclosed sides also add a modest security benefit by reducing visibility of stored items, though they are not a substitute for a locked garage.
Do Metal Carports With Sides Protect From Wind and Rain?
Yes, but the level of protection depends on how many sides are enclosed and the roof style. A three-sided metal carport with a vertical roof provides strong protection from wind-driven rain in most residential conditions. The vertical roof panels run from peak to eave, channeling water off quickly and reducing the chance of pooling or leaking at panel seams.
Side panels rated for 90 mph or higher wind loads (check the manufacturer’s engineering certification) are appropriate for most U.S. regions. Coastal areas or tornado-prone zones may require engineered structures rated for 130 mph or more.
Key protection factors:
- Roof style: Vertical roof sheds water and snow best; regular roof is the weakest option.
- Panel overlap: Properly overlapping side panels with sealed screws prevent wind-driven rain infiltration.
- Anchoring: A structure that shifts or lifts in wind fails regardless of panel quality. Use concrete anchors or auger-style ground anchors rated for your wind zone.
Can I Install a Metal Carport With Sides Myself?
Most single and double-car metal carport kits with sides are designed for DIY installation by two adults with basic hand tools over one to two weekends. Manufacturers typically include numbered components, pre-drilled holes, and step-by-step instructions.
DIY is reasonable when:
- The structure is 18 feet wide or less
- You have a level, prepared surface (concrete, gravel, or compacted soil)
- Local wind and snow loads are moderate
- You have help from at least one other person
Hire a professional when:
- The structure exceeds 20 feet in width or 30 feet in length
- You are in a high-wind or heavy-snow zone
- The site requires significant grading or a new concrete slab
- Your permit requires an engineer’s stamp on the installation
One practical note: the most common DIY error is misaligning the base rails before anchoring, which causes doors and panels to fit poorly. Take extra time to square the base before any fasteners go in.
What Vehicles Fit Best Under a Metal Carport With Sides?
Metal carports with sides accommodate a wide range of vehicles, from standard passenger cars to full-size RVs, depending on the dimensions ordered. The key is matching the structure’s width, height, and length to the vehicle’s actual measurements with clearance room added.
General sizing guide:
- Single passenger car: 12×20 feet, 8-foot leg height
- Full-size truck or SUV: 14×20 to 18×20 feet, 10-foot leg height
- Boat on trailer: 12×30 to 14×35 feet, 10-12 foot leg height
- Class A or C RV: 14×40 to 18×50 feet, 14-16 foot leg height
- Farm equipment (tractor, combine): Custom widths up to 30 feet, 16+ foot legs
Always measure your vehicle at its widest and tallest points, then add at least 2 feet of clearance on each side and 2 feet of overhead clearance. This prevents door dings, panel scrapes, and difficulty maneuvering.
Are Metal Carports With Sides Good for RV and Boat Storage?
Metal carports with sides are one of the most cost-effective long-term storage solutions for RVs and boats. They protect the vehicle from UV degradation, bird droppings, tree sap, and weather while costing a fraction of a full enclosed metal building.
For RV storage specifically, a three-sided structure with an open front allows easy pull-through access. A vertical roof is strongly recommended because RV roofs are flat or slightly curved and collect standing water if the carport roof does not drain efficiently.
For boats, the primary concern is protecting the hull finish and canvas covers from UV and moisture. A two- or three-sided structure keeps rain and sun off the boat while allowing airflow to prevent mildew under tarps or covers.
Boat and trailer tip: Order a structure at least 4 feet longer than the trailer tongue-to-tail measurement. Trailer tongues extend further forward than most buyers anticipate, and you need room to hitch and unhitch safely.
What Permits Do I Need for a Metal Carport With Sides?
Permit requirements for metal carports with sides vary by municipality, but most jurisdictions in the United States require at least a building permit for any permanent structure. Some counties also require a zoning variance if the structure is within a certain distance of property lines or in a residential HOA area.
Steps to take before ordering:
- Contact your local building department or county zoning office.
- Ask specifically about permits for accessory structures and whether a concrete foundation is required.
- Request the wind and snow load requirements for your area (manufacturers can then certify the structure meets those specs).
- Check HOA rules if applicable; some associations prohibit visible metal structures or require specific colors.
- Submit your permit application with the manufacturer’s engineering drawings, which reputable companies provide.
Skipping permits is the single most consequential mistake buyers make. An unpermitted structure can result in fines, forced removal, and complications when selling your property.
How Do Metal Carports With Sides Compare to Wooden Garages?
Metal carports with sides cost significantly less than wooden garages, assemble faster, and resist rot, termites, and mold. A comparable wooden garage typically costs two to four times more when accounting for materials, framing labor, and finishing. However, wooden garages offer better insulation, more design flexibility, and higher perceived property value in most real estate markets.
| Factor | Metal Carport With Sides | Wooden Garage |
|---|---|---|
| Cost (double-car) | $2,000-$5,000 | $8,000-$25,000+ |
| Assembly time | 1-3 days | 1-3 weeks |
| Lifespan | 20-30+ years | 30-50 years (with maintenance) |
| Maintenance | Low | Moderate to high |
| Insulation | Minimal | Good (with added insulation) |
| Pest resistance | Excellent | Poor without treatment |
| Permit complexity | Low to moderate | Moderate to high |
Choose a metal carport with sides if you need affordable, fast protection for vehicles or equipment and do not require a finished interior workspace. Choose a wooden garage if you want a heated workshop, finished storage space, or maximum curb appeal for resale value.
How Long Do Metal Carports With Sides Typically Last?
A properly installed and maintained metal carport with sides made from galvanized or Galvalume steel typically lasts 20 to 30 years. Some manufacturers offer 20-year rust-through warranties on their panels, which is a reasonable benchmark for expected structural longevity.
Lifespan depends heavily on:
- Steel gauge: 12-gauge outlasts 14-gauge in harsh climates.
- Coating quality: Galvalume and high-grade painted finishes resist corrosion longer than bare galvanized steel.
- Anchoring: Structures that shift or vibrate in wind wear at connection points faster.
- Climate: Coastal salt air, high humidity, and freeze-thaw cycles accelerate corrosion without proper coatings.
What Maintenance Do Metal Carports With Sides Require?
Metal carports with sides require minimal but consistent maintenance. The primary tasks are cleaning, inspecting fasteners, and touching up any scratched or chipped paint before rust can establish.
Annual maintenance checklist:
- Rinse the entire structure with a garden hose to remove dirt, bird droppings, and organic debris.
- Inspect all self-tapping screws and replace any that are loose or showing rust.
- Check the roof panels for lifted edges or gaps at seams, especially after major storms.
- Apply a rust-inhibiting touch-up paint to any scratches or bare metal spots.
- Clear debris from the roof valley (on vertical-roof styles) and ensure drainage is unobstructed.
- Re-check anchor bolts or ground anchors for tightness, particularly after hard freezes or wet seasons.
A well-maintained metal carport with sides requires roughly two to four hours of attention per year, making it one of the lowest-maintenance vehicle shelter options available.
Common Mistakes People Make When Buying Metal Carports With Sides
The most frequent buyer errors fall into four categories: undersizing, under-specifying steel gauge, ignoring local code, and choosing the wrong roof style.
Avoid these specific mistakes:
- Ordering based on vehicle length alone: Tongue weight, trailer hitches, and door swing all require extra length. Add at least 4 feet to your longest vehicle measurement.
- Choosing 14-gauge steel in a high-wind or snow zone: The cost difference between 14-gauge and 12-gauge is modest; the structural difference in severe weather is significant.
- Skipping the vertical roof upgrade: Regular and boxed-eave roofs cost less but accumulate water at horizontal panel seams, leading to leaks within a few years.
- Not anchoring to a hard surface: Carports anchored only to soft soil can shift or lift in high winds. Concrete anchors or helical ground anchors are worth the added cost.
- Assuming HOA approval: Always get written HOA approval before ordering. Verbal approval is not enforceable.
Frequently Asked Questions About Metal Carports With Sides
Q: Can a metal carport with sides be converted into a fully enclosed garage later?
Yes. Most reputable manufacturers design their carport frames to accept additional panels and doors. You can add a front roll-up door and a fourth side panel to convert a three-sided carport into a fully enclosed metal building, often without replacing the frame.
Q: What is the best steel gauge for a metal carport with sides?
12-gauge steel is the best choice for most applications, especially in areas with high wind or snow loads. 14-gauge is acceptable in mild climates for light-duty use, but the price difference rarely justifies the reduced strength.
Q: Do metal carports with sides require a concrete foundation?
Not always. Many installations use ground anchors driven into compacted soil or gravel. However, a concrete slab provides the most stable base, simplifies anchoring, and is often required by local building codes for permanent structures.
Q: How wide should a metal carport with sides be for two full-size trucks?
A minimum of 22 feet wide is recommended for two full-size trucks parked side by side, allowing enough room to open doors without hitting the side panels. 24 feet is more comfortable.
Q: Are metal carports with sides fire-resistant?
Steel is non-combustible, so the structure itself will not fuel a fire. However, the panels can warp or collapse under extreme heat. Metal carports with sides are generally considered safer than wood-framed structures in wildfire-prone areas.
Q: Can I add electricity or lighting to a metal carport with sides?
Yes. Many homeowners run conduit along the frame to add LED lighting, outlets, or a ceiling fan. This work typically requires an electrical permit and should be done by a licensed electrician.
Q: Do metal carports with sides add value to a property?
They add functional value and can be a selling point for buyers who need vehicle storage. However, they generally do not add assessed property value the way a permitted attached garage does. An unpermitted structure can actually complicate a sale.
Q: What colors are available for metal carports with sides?
Most manufacturers offer 10 to 20 standard colors for both panels and trim. Popular choices include Galvalume (silver), charcoal gray, barn red, and hunter green. Custom colors are available from some suppliers at an added cost.
Q: How long does delivery take for a metal carport with sides kit?
Standard lead times in 2026 run from 2 to 8 weeks depending on the manufacturer, customization level, and regional demand. Fully custom or large RV-size structures may take 10 to 14 weeks.
Q: Can a metal carport with sides withstand heavy snow loads?
Yes, if the structure is rated for the snow load in your area. Always request the manufacturer’s engineering certification showing the pounds-per-square-foot (PSF) snow load rating, and match it to your local ground snow load data from your building department.
Conclusion
Metal carports with sides represent a practical middle ground between a bare open carport and a full enclosed garage. They cost far less than a wooden or steel garage, go up in days rather than weeks, and provide meaningful protection for vehicles, RVs, boats, and equipment that an open frame simply cannot match.
Actionable next steps for 2026:
- Measure your largest vehicle at its widest, tallest, and longest points before requesting any quote.
- Call your county building department and get permit requirements in writing before placing an order.
- Request engineering certification documents from any manufacturer you consider, confirming wind and snow load ratings for your region.
- Choose a vertical roof style and 12-gauge steel as your baseline specification, then adjust down only if budget truly requires it.
- Budget for anchoring, delivery, and permit fees in addition to the kit price.
- Get at least two to three quotes from manufacturers who offer site-specific engineering drawings.
A well-chosen, properly permitted metal carport with sides will serve reliably for two decades or more with minimal upkeep. The key is making informed decisions at the front end rather than correcting avoidable mistakes after installation.
